Bedford built a twin-engined artic tractor in the late 1960s.
The engines were side by side in a 'spread' chassis frame and connected together by a morse chain drive.
First (and only) time out it accelerated steadily up Cutenhoe Road Luton from the factory, but by the time it reached the Chaul End Test Track at Caddington it had twisted the frame (insufficient cross-bracing) and you could slide a housebrick (on end) under the right front wheel . . .
